"A moment ago This company is great. Roy Villa the service technician was very knowledgeable. No threat of up selling. Just explained what was wrong with the heating system and fixed it. This is for a rental house. He told me about the warranty plan they have for heating and AC. It was extremely reasonable. Now I will just have the AC and heater checked before each season."

"We hired Airmercia Air Conditioning & Heating to evaluate our heating system and propose repair solution. Ryan was very professional and punctual. He did not make any force sales. He just offered various repair and replacement solutions and explained pros and cons for each one. We decided to replace our furnace and duct system. Ryan did an excellent Job!! I highly recommend him for your HVAC project."

"I had been told by another company that my HVAC unit needed to be replaced for $3500.  However, the technician didn't even look at the unit.  So I subscribed to Angie's list and chose Liberty for a second opinion.  Apparently all that was needed was to add coolant; the level was very low.  My AC is now working better than ever.  Thank you Liberty and Angie's list for saving me over $3000!

"Technician Angel came on time. He first cleaned our HVAC unit, checked the wirings & parts & performed tests to ensure the unit is running according to standards. He inspected the Air ducts, vents even the attic. He explained everything and showed us the pictures that he took & the results on HVAC heating and cooling tests that were done. Overall a very good job done by Technician Angel I told him to come back after 6 months. Already recommended Airtime Heating & Cooling to my neighbor. 5 STARS"

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"Friendly customer service and professionalism. Two guys serviced the unit and check each room in the house, as well as the inside returns and filters. They made recommendations regarding vent settings and leaving room doors open to improve return airflow."

Heating and Air Conditioning questions, answered by experts

You need to know the square footage of your home first. Multiply that number by 20, which will get you the BTUs (British Thermal Units) needed to cool your home efficiently. Homes up to 1,000 square feet usually need a 1.5-ton unit; homes 1,000 to 1,200 square feet usually need a 1.75-ton unit, and homes 1,200 to 1,400 square feet usually need a 1.9-ton unit. Talk to a local pro for more specific advice on your home. 

Yes, through thorough cleaning and inspection, optimizing functionality, and reducing energy use.

Signs of a damaged evaporator coil include warm air from vents, frequent starts and stops without proper cooling, failure to turn on, refrigerant leaks, and unusual noises. If you suspect issues with your AC system or its components, it’s best to call an AC repair technician for proper diagnosis and repairs.

Yes, you can run an attic fan with the AC on. In fact, you don’t have a choice with a passive attic fan. Plus, when an attic fan draws out hot air from the attic, it helps regulate the temperature of your whole home, so your AC doesn't have to work as hard.

The general rule of thumb for figuring out how much AC tonnage you need in your home is that for every 500 to 600 square feet of space you need to cool, you’ll need one ton of AC cooling power. So, a 1,000-square-foot home will need 2 tons of AC power.
